Title: Biochemical treatment of steel mill drainage
Inventor: NOMURA YUKIHIRO
IPC: C02F3/34
Filed: 1994-07-21
Abstract: PURPOSE:To recover iron oxidized into ferric ion effectively by the action of an iron oxidation bacterium. CONSTITUTION:An iron oxidaizing bacterium is cultured using a ferrous sulfate solution obtained from sludge in a mixed acid pickling line. An acclimating process is repeated using the iron oxidizing bacteria while increasing the amount of ferrous chloride, chromic acid and hydrochloric acid gradually in the ferrous sulfate solution. Next the acclimated iron oxidizing bacteria are used for the oxidation at pH value of 1 to 4 of the mixed acid pickling line drainage, and thus a ferrous ion is oxidized into a ferric ion to recover iron. In this treatment, the concentration of the ion content should preferably be 4,000mg/l or less for chlorine, 80mg/l or less for trivalent chromium, 2,000mg/l or less for zinc, and 100mg/l or less for tin. If the concentration exceeds this optimum range, the oxidation efficiency of ferrous ion is deteriorated.

Filed: 1985-08-29
Abstract: PURPOSE:To obtain an egg white hydrolyzate without bitterness, by treating egg white liquid with protease, ultrafiltering the resultant crude egg white hydrolyzate through a specific filtration membrane and collecting the resultant ultrafiltrate. CONSTITUTION:Egg while liquid is treated with protease to give crude egg white hydrolyzate, which is then ultrafiltered through an ultrafiltration membrane giving about 8,000-20,000 fractionated molecular weight. The resultant ultrafiltrate is then collected to afford the aimed hydrolyzate. The amount of the proteolytic enzyme to be added is suitably 0.1-6% based on the egg white liquid depending on the kind of the enzyme to be used. Preferably, the temperature of the protease treatment is 45-55 deg.C, and the treating time is 2-10hr. The egg white liquid to be used may be raw egg white liquid obtained by breaking hens'eggs, etc., and separating the egg yolk or thawing frozen egg white or dissolving dried egg white in water, etc. If the amount of the egg yolk mixed in the egg white liquid is large, the ultrafiltration carried out later is not readily carried out by the influence of phospholipid, etc., contained in the egg yolk. Therefore, egg white liquid containing little egg yolk mixed therein is preferably used.

Abstract: PROBLEM TO BE SOLVED: To suppress the arrival delay of picture data of one frame picture resulted from retransmission control by controlling generated code quantity on a transmission-side by means of a controlled variable corresponding to the arrival time of picture data of one frame picture to a reception-side. SOLUTION: The reception-side 200 detects errors in a frame unit by a channel error detection means 10 and returns a frame number where the error is detected to the transmission-side 100 as a re-transmission request signal.

A picture encoding interval control means 5 calculates a picture encoding interval from a value which is inputted from the counter 6 and the generated code quantity of the previous frame picture.  The picture encoding means 1 compresses/encodes input picture data by using the calculated quantized step and the calculated picture encoding interval.

IPC: H01J37/20
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a scanning type electron microscope capable of enhancing vibration resistance of a sample moving stage so as to improve resolution. SOLUTION: Oil is introduced into a reciprocating type hydraulic cylinder 103 from a hydraulic source (not shown) through a port 106a. A lock shaft 105 is pressed against a lock plate 107 by the hydraulic pressure so as to restrict motion of a tilt table 108. A column 109 made of a material having a great friction coefficient with respect to the lock plate 107 is fixed at the tip of the lock shaft 105, thereby achieving surface contact with the lock plate 107. The oil is introduced into the reciprocating type hydraulic cylinder 103 through a port 106b, and then, the lock shaft 105 is drawn back by the by hydraulic pressure to release stage lock. Consequently, rigidity in an x direction becomes large and friction force in y and z directions become large, thus effectively suppressing vibration in the x, y and z directions of the tilt table 108.

Filed: 1987-07-30
Abstract: PURPOSE:To decreases the deciding frequency and to ensure the smooth input/ output of data by deciding the flags for each transfer of a prescribed block via a circuit set at the reception side. CONSTITUTION:The data divided into blocks are written (DI1-DIM) into and read (DO1-DOM) output of a memory 1 for each prescribed number of data words. Then the write clocks SI and the read clocks SO are supplied to a 1st shift register 2 every data word and a write request flag, the inverse of IR is delivered from a stage set at the other side of the register 2. While the write clocks BSI and read clocks BSO are supplied to a 2nd shift register 3 and a read request flag, the inverse of OR is delivered from a stage of one of both sides of the register 3 every block for transfer of blocks. Thus a circuit set at the reception side is just required to judge the flag at every transfer of a prescribed block. As a result, the deciding frequency is decreased and the smooth input/output of data are secured.
